Hello pbguy,
I've updated the values of a table with this abs like this
initially the records are like this
name credit
A -9
B -8
c -5

now i've updated the table like this

update mytable set credit=abs(credit)

now the values are like this

name credit
A 9
B 8
c 5

is it now possible to change all the values with - again?

thank you very much...
